Manifold cracks or gasket leaks, loose connections, internal parts in muffler or cats loose, rusted out.


May be just a heat shield or exhaust rattling against something, Just go to an exhaust shop to have it checked out.


Look for a loose heat shield and hope you find one...that would be a cheap fix
